We consider the problem of choice of norms in discrete approximation. First, we describe properties of the standard l 1, l 2 and l ∞ norms, and their essential characteristics for using as error criteria in discrete approximation.

After that, we mention the possibility of applications of the so-called total least squares and total least l p norm, for finding the best approximation. Finally, we take a look at some nonstandard, visual error criteria for qualitative smoothing.
